Synthesis, structure and electrochemical characterization of a new non-oxo vanadium(IV) complex
Abstract
Reaction of N,N,N′,N′-tetrakis(2-hydroxybenzyl)ethylenediamine (H4tben) with VCl3 in tetrahydrofuran in the presence of Et3N affords [Et3NH][VIII(tben)] which is oxidized by oxygen to the stable [VIV(tben)] complex; the X-ray crystal structure, and the electrochemical, magnetic and electronic spectroscopic properties of [VIV(tben)]·CH2Cl2 are reported.
